a) 5% loss
b) 10% gain
c) 15% loss
d) 20% gain
Answer: b
Explanation:
2750 Cost Price = 2500 Selling Price
$$\eqalign{
& \frac{{{\text{CP}}}}{{{\text{SP}}}} = \frac{{2500}}{{2750}} = \left. {\frac{{10}}{{11}}} \right\rangle {\text{1 unit profit}} \cr
& {\text{Profit}}\% = \frac{1}{{10}} \times 100 \cr
& \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 10\% {\text{ gain}} \cr} $$
